Where to go in Santiago...

If a friend comes from other country the first place I'll take him is Cerro San Cristóbal. Here we can go up by the funicular or walking through the Cerro. When we arrive to the peak of the mountain we can see the Virgin and all Santiago. Then we'll return down and have a launch in some restaurant in Bellavista. And go home to take a rest. At night we can go out to Plaza Ñuñoa and drink and eat something in one of the restaurants that we can find here. After this get a ticket for a disco It would be really good. And spend the night dancing and meeting people.
To the other day maybe go to a mall and have a relaxing day.
Cordillera de los Andes is also a good place to visit. It will depends of the season. In winter of course is better. Going to this place we can have a really good time with the snow and everything we can do with it. In summer we can go up but just to see the mountain how big it is.
Other thing to do is going to a soccer match. Between the most populars team in Chile. Colo-colo and U. Chile.
Other place in Santiago where we can visit is Cajon del Maipo. A nice place to go in winter and in summer. Here we can a find a river and camping near from it. And a have a nature day. Also we can find rafting and climbing. So we can add a extreme day if we want.
Theres a lot of mountains where we can climb. Like cerro Manquehue. Provincia, Pochoco. Good places to go. And easy ones.
Now in Santiago exist a lot of routes for trekking and running. So this is another idea that we can use with a friend.

Well. I guess this is everything I got.
I hope you like it.
